Kyrill caused widespread damage across Western Europe, especially in the United Kingdom and Germany. 47 fatalities were reported, as well as extensive disruptions of public transport, power outages to over one hundred thousand homes, severe damage to public and private buildings and major forest damage through windthrow.

The storm was named "Kyrill" on 17 January 2007 by the Free University of Berlin's meteorological institute.[3] The storm was named after a Bulgarian man living near Berlin, whose family donated to the university's "Adopt-A-Vortex"[5] programme.[6]

Kyrill was unusual in that its field of hurricane-force winds was very broad, affecting large areas of Germany as well as neighbouring countries at one time. Kyrill brought wind gusts of up to 130 km/h (80 mph) even in the North German plains. German weather experts have described the storm as a "once in a decade" event.

After making landfall in Ireland and the UK in the late hours of 17 January 2007, the storm swept across Ireland and Great Britain on the night of 17 to 18 January, with winds of 160 km/h (99 mph) at The Needles, 149 km/h (93 mph) recorded in Dublin, 130 km/h (81 mph) recorded at Aberdaron on the Lleyn peninsula, 122 km/h (76 mph) at Mumbles near Swansea and winds of 101 km/h (63 mph) at St Athan in the Vale of Glamorgan. The German Meteorological Service had advised people to stay indoors and avoid unnecessary trips on 18 January,[7] and wind strengths of up to 12 on the Beaufort scale were seen across the Netherlands and Germany as the storm made landfall. The storm moved across the German states of Lower Saxony, Bremen, Hamburg, Schleswig-Holstein and North Rhine-Westphalia first, then spread across the whole country in the evening hours of 18 January. Wind gusts as high as 202 km/h (125 mph) on the Wendelstein and 198 km/h (123 mph) on the Brocken in the Harz mountains were recorded.[8] The storm then moved eastwards, its center crossing Lower Saxony between 18:00 and 19:00 CET, moving toward the Baltic sea, its cold front spawning several tornadoes in Germany, three of which have been confirmed as of 22 February.[9] In the Czech Republic the highest wind speed was measured on Sněžka in the Krkonoše mountains, where wind gusts reached 212 km/h (132 mph).[10] In the Czech Republic winds as high as 200 km/h disrupted both rail and air traffic; record high temperatures reached 14 °C (57 °F) in Prague.[11]

On the day of the landfall, an approximate 25,000 homes in southern England were without electricity after electricity pylons were damaged by the storm.[12] Same day, the German states of Brandenburg, Saxony and Saxony-Anhalt were hit by a massive power cut. 52,000 homes were without energy, according to local utility envia.[13] The German district Siegen-Wittgenstein had issued a state of emergency, with schools remaining closed on Friday, 19 January, and roads not to be cleared right away, but closed instead until the situation improved.[14] By the second day of the storm, more than one million homes were left without power in the Czech republic with another million households without electricity in Germany and tens of thousands dark homes in Austria and Poland.[15][16] In Poland, a flood alarm was issued in several localities due to large rainfalls and the storm damaged several houses in the region of Jelenia Góra.[17] In Ukraine, the supply of oil through the Druzhba pipeline came to a complete halt as a result of the storm.[18] Strong winds over the Alps became foehn wind and caused unseasonally high temperatures in Italy (up to 25 °C/77 °F in Turin).[19]

In Ireland thousands of homes were left without power and heavy downpours caused flash flooding.

In the Netherlands, the storm flood warning system (Stormvloedwaarschuwingsdienst) was activated, as the approaching storm was measured in excess of 10 Beaufort. Alarms were issued to two northern regions, Delfzijl & Harlingen, at approximately 22:30 CET on Thursday 18 January. The water level peaked in the early hours of Friday, almost 4.5 m above the astronomical prediction level.

High winds in the Alps prompted the Austrian weather service to advise the skiers and snowboarders to seek shelter, and caused at least one major motorway tunnel closure.[20]

The cost of the damage across Europe to the insurance industry has been estimated by Swiss Re as €3.5bn.[21] In the UK, the cost to the insurance industry could be as high as £350m (€520m).[22] As the event is relatively recent for the insurance industry these are unlikely to be the final costs.

Several windows were broken at the Römisch-Germanisches Museum in Cologne, Germany by plywood that was covering a fountain near Cologne Cathedral. The wood caused major damage to the encasing of a Romanmosaic dating to the 3rd century. The Römisch-Germanisches Museum building was originally constructed around the mosaic. As of January 2007, it is still unclear whether the mosaic has suffered damage, as museum staff have announced the clean-up will at least take a week due to the fragility of the exhibit.[23] Museum manager Bernhard Ostermann estimated that the mosaic was damaged in 100 to 150 places[24]

The container shipMSC Napoli, whilst on its way to Portugal carrying 2,394 containers, of which 158 were classed as hazardous substances, had to be abandoned in the English Channel on the 18th. The crew of 26 were picked up by British and French rescue services. The next day the Napoli was under tow for repair at Portland Harbour in Dorset, but with forecasts of further high winds it was taken to shelter in Lyme Bay. The ship had suffered structural damage, including a 1 m by 0.5 m (3 ft by 1 ft 6 in) hole on the starboard side and water flooding and had to be beached in the bay 1-mile (1.6 km) off the East Devon coast at Branscombe[25] The ship leaked oil, sparking a clean-up operation, and widespread reporting in the national news led to the wreck temporarily becoming a tourist attraction and subject to scavenging from the containers which washed up on the beach.[26] The wreck was subject to a complex break-up operation which was not complete until July 2009.

The ferry services between Fishguard and Rosslare were cancelled,[27] as well as the ferries to Heligoland and most West Frisian Islands, East Frisian and North Frisian islands.[28] In Ireland, Dublin Port was forced to completely close for a time – the first time in history the port has closed. Two fishing vessels sank at sea, with a total loss of seven lives. A third vessel engaged in the rescue attempts also sank but the crew were rescued.[29] A storm tide with sea levels of up to 3.5 metres (11.5 ft) above mean tide was announced for the coastal areas of Lower Saxony and Schleswig-Holstein by the state governments,[30] however the storm had already passed those areas before high tide had set in, so there was less damage than expected.

The Cypriot-flagged freighter Golden Sky, carrying a load of fertiliser and fuel oil, ran aground near Ventspils, off the coast of Latvia; the ship's crew were rescued in a joint Latvian and Swedish operation.[31][32]

Many countries suffered from road and motorway closures. In the United Kingdom, the major motorways M1, M6 and M18 were closed in several places, as well as the M25 ring road around London and a number of other motorways. Bridges including the M6 Thelwall Viaduct in Warrington, the M25 Dartford Crossing in London and the M1 Tinsley Viaduct in Sheffield were closed due to high winds. All Pennine Passes were closed. Closures were largely due to the toppling of multiple high-sided vehicles. Other motorways were affected by significant delays. Long queues developed around blackspots, in particular replacement crossings of the Manchester Ship Canal including routes through Warrington and over the Runcorn Bridge.[33] In Germany, a number of motorways, especially those with bridges over the Rhine or those with valley bridges, also faced closures due to high winds. The Dutch police advised drivers of empty lorries not to enter the Netherlands. Many roads were also closed in Ireland due to fallen trees and overturned lorries.

More than 280 flights were cancelled at Heathrow airport, over 120 flights were cancelled at Doncaster Sheffield Airport and 80 more flights were cancelled due to health and safety reasons at Manchester Airport.[34] Many flights were delayed at Ireland's airports on the morning of 19 January due to the high winds in Ireland, however by afternoon they were delayed because of high winds elsewhere in Europe. Several flights at Frankfurt International Airport were cancelled due to the bad weather.[35] Overall, during 18 and 19 January Swiss International Air Lines announced the cancellation of at least 88 flights, British Airways cancelled 180 flights and Lufthansa cut 329 flights and warned of more delays before the service began to return to normal.[36]

In the Netherlands, all train services ceased operating on the evening of 18 January. The station in Delft and the central station in Amsterdam were evacuated due to roof damages.[38] A train driver sustained minor injuries when his train hit a tree that had fallen onto the railway near Venlo.

German railway operator Deutsche Bahn at first limited the maximum speed of its trains to 200 km/h (124 mph),[35] then all services on the domestic InterCity/InterCityExpress network as well as the local services in Northern and Western Germany were discontinued from 17:15 CET on 18 January onwards, as major main lines (Bremen-Hannover, Hamburg-Hanover, Bremen-Osnabrück) and many branch lines were affected by the storm. In an unprecedented move, Deutsche Bahn discontinued virtually all train services in Germany at 19:30 CET until further notice, with only very limited local services running on a per-line decision basis. Trains currently on the lines would stop at the next station and stay there, leaving passengers stranded all over Germany in the tens of thousands. Later, as the situation was worsening, trains were left open for those passengers unable to find a hotel to sleep in. In major affected stations, such as Münster and Hanover, air raid shelters in the stations were opened up for the night, with the Red Cross issuing blankets to stranded passengers.[39] Train services were resumed on the morning of 19 January, but cancellations and delays continued during the weekend as 34,000 kilometres (21,100 mi) of track needed to be checked and cleared. The DB was faced by the massive challenge of getting its network into working order again after coming to a full stop during the night, the first such event ever to happen on the German railway network in peacetime.[40] On 18 January, an InterCity train ran into a tree that had fallen onto the tracks between Elmshorn and Westerland. One of the locomotives was damaged, no casualties were reported. An InterCity train with 450 passengers on board was stuck near Diepholz and had to be evacuated, Duisburg Hauptbahnhof station was suffering from a power outage as the result of a grid failure.[13]

Late on 18 January, the main railway station in Berlin suffered from major structural damage. A two-ton girder fell from a height of 40 metres (130 ft), damaging an outside stairwell. The station was completely evacuated, as glass plates from the façade were coming loose and falling to the pavement below.[41] On the early afternoon of 19 January, the station was opened to the public again.[8] Discussion started as to whether the eight-month-old station was suffering from design failures, but these claims were rejected by both Deutsche Bahn and the architect. The girders provide no means of structural support and are, for architectural reasons, only lying on small supports similar to a shelf and not permanently fixed in place. The DB claimed that it will address the problem by welding additional supports in front of the girders, and that they would close the station at winds exceeding 8 bft until the problem was resolved. On the afternoon of 21 January 2007, the station was closed again to the public due to heavy winds at the time.[42] and remained closed until 20:00 CET.[43] Some politicians have suggested opening Berlin's Bahnhof Zoo for long-distance services again to have an alternative to Hauptbahnhof in cases of bad weather until the problem has been addressed, but the Deutsche Bahn has refused these suggestions on the claims that they would be both unfeasible and unnecessary.

One of the quickest spreading computer worms of all time appears to have been named for this event. The Storm Worm causes massive amounts of spam to appear on a user's computer. Some of the emails that appear reference Kyrill in them.[44]
